FIELD

The present invention relates to the field of milling products and particularly to a whole grain flour and products including same.

BACKGROUND

Refined wheat flour (white flour) is used to produce a wide range of popular bakery and snack products. Products made from refined wheat flour traditionally have a uniform, light-colored appearance and smooth (non-gritty) texture. Comparatively, products made with traditional whole grain wheat flour, tend to have a coarser, more dense texture and a darker, less consistent appearance (ex. —visible bran specks). Currently existing whole grain wheat flours (i.e., whole wheat flours) may be prepared, for example, by grinding cleaned wheat, other than durum wheat and red durum wheat, which, once ground, has a particle size wherein not less than 90% passes through a 2.36 millimeter (U.S. Wire 8) sieve and not less than 50% passes through an 850 micrometer (U.S. Wire 20) sieve. In whole wheat flour (whole grain wheat flour), the proportions of the natural constituents in the wheat, other than moisture, remain unaltered as compared to the wheat kernels. Bread is considered to be 100% whole wheat when the dough is made from whole grain wheat flour, bromated whole wheat flour, or a combination of these. No refined wheat flour is used in whole wheat products. Whole grain wheat flour has increased nutritional value compared to refined wheat flour because it includes the entire wheat kernel, (i.e., includes bran, germ, and endosperm) rather than primarily just the endosperm, as shown in FIGS. 1 and 2. Thus, whole grain wheat flour is higher in fiber, protein, lipids, vitamins, minerals, and phytonutrients, including phenolic compounds and phytates, when compared to refined wheat flour. Further, compared to whole grain wheat flour, refined wheat flour is higher in calories and starch, while containing only about a fifth of the dietary fiber found in whole grain wheat flour and less protein than whole grain wheat flour, as shown in FIGS. 1 and 2. Even enriched refined wheat flour, which may contain thiamin, riboflavin, niacin, folic acid and iron added at or above the levels found in the wheat kernel, does not include as much fiber, minerals, lipids, and phytonutrients, as are found in whole grain wheat flour.

Recently, health practitioners have been promoting the benefits of whole grain foods. The importance of increasing whole grain consumption is reflected in the changes in recommendations set forth by government and health organization expert groups. In the Healthy People 2010 Report (National Academy Press, 1999), it is recommended that for a 2,000 calorie diet individuals two years and older should consume at least six daily servings of grain products with at least three being whole grains. In the 2005 Dietary Guidelines for Americans it is recommended that consumers should eat 3 or more ounce equivalents of whole grain foods each day, with the rest coming from enriched or whole grain flours. In general, at least half of the intake should come from whole grains. The American Heart Association, American Diabetes Association and the American Cancer Society also make specific recommendations regarding increasing the consumption of whole grains.

Despite the well-documented nutritional advantages of eating whole grain products as compared to refined flour products, consumers often prefer the consistent texture and light color of products containing refined wheat flour. Currently, in the United States, consumption of white bread made from refined wheat flour is greater than that of whole wheat bread. Such consumer preference for refined flour products may limit the use of current whole grain wheat flours in bakery and snack products.

Another limitation of current whole grain flours involves their shelf life. The bran and germ of whole grain wheat flour contain enzymes such as lipase, lipoxygenase, and peroxidase. These enzymes are important during early plant development, but their presence in the whole grain wheat flour reduces the shelf life of the whole grain wheat flour.

Previous “traditional” whole grain flourmills (as shown in FIG. 3) are only capable of producing a few types of granular whole grain flour products and have not been able to produce whole grain wheat flour having similar baking attributes and resulting in products similar to refined wheat flour. Using current technology, the finest granulation of whole grain wheat flour that is available in the marketplace has a particle size larger than refined wheat flour. Attempts have been made to produce a whole grain wheat flour with a particle size comparable to refined wheat flour, however, these attempts generally have not been economically feasible, and did not result in a particle size that was comparable to refined wheat flour. The current processes are uneconomical due to the energy usage and capitalization required to grind the millfeed using the rollermills, hammermills and bran slicers typically implemented in such processes. Therefore, such processes cannot economically achieve the desired granulation.

Given that a number of popular consumer products made with refined wheat flour are low in fiber and do not have the nutritional benefits of their respective whole grain counterparts, it would be desirable to develop a whole grain wheat flour that can be used in these products, yet still allow these products to maintain a desirable texture and appearance that is acceptable to consumers. Such products would have enhanced nutritional value and increased shelf life, while retaining the qualities (ex. —baking attributes, appearance, color, taste, texture) that appeal to a large segment of consumers.

Further, in the United States, individuals typically consume 12-15 grams of fiber per day, which is half or less of the recommended level. Many current fiber supplements have an undesirable texture, taste and have limited nutritional value beyond their fiber content. Current fiber supplements including isolated fibers may have a less than desired nutrient content. Therefore, it would also be desirable to develop nutritious, high fiber food products and fiber supplements which have a texture and taste more palatable to a number of consumers.

DETAILED DESCRIPTION

In an exemplary embodiment, the present invention is directed to a whole grain flour (ex. —an ultrafine-milled whole grain flour, such as an ultrafine-milled whole grain wheat flour; a whole grain wheat flour, or a flour made from about 100% of the grain). For example the grain may include, but is not limited to at least one of: wheat, sorghum, milo, triticale, emmer, einkorn, spelt, oats, corn, rye, barley, rice, millet, buckwheat, quinoa, amaranth, African rice, popcorn, teff, canary seed, Job's tears, wild rice, tartar buckwheat, variants thereof, and mixtures thereof. The whole grain flour includes a refined flour constituent (ex. —refined wheat flour or refined flour) and a coarse fraction (ex. —an ultrafine-milled coarse fraction). In a current embodiment, the nutritional composition of the whole grain flour of the present invention may be identical to that of whole grain wheat flour. (as shown in FIG. 8). For example, the whole grain flour of the present invention may contain about 8-17% protein, about 2% fat, about 2% ash (minerals), and about 60-80% total carbohydrates, including about 12% total dietary fiber. Thus, the whole grain wheat flour (ex. —ultrafine-milled whole grain wheat flour) of the present invention contains less protein, fiber, vitamins, minerals, and phytonutrients, compared to the coarse fraction of the present invention. (FIG. 8).

Refined wheat flour may be flour which is prepared, for example, by grinding and bolting cleaned wheat other than durum wheat and red durum wheat. The Food and Drug Administration (FDA) requires flour to meet certain particle size standards in order to be included in the category of refined wheat flour. The particle size of refined wheat flour is described as flour in which not less than 98% passes through a cloth having openings not larger than those of woven wire cloth designated “212 micrometers (U.S. Wire 70)”. In an exemplary embodiment, as shown in FIG. 8, the refined wheat flour is typically comprised of about 10-11% protein, about 1% fat, about 76% total carbohydrates, which includes about 2.5-3% dietary fiber, and about 0.5% ash (minerals). In present embodiments, the refined flour constituent may be enriched flour. According to the FDA Code of Federal Regulations (CFR), enriched flour is refined wheat flour which contains 2.9 mg of thiamin, 1.8 mg of riboflavin, 24 mg of niacin, 0.7 mg of folic acid and 20 mg of iron added per pound of refined wheat flour. Enriched flour may also contain calcium in the amount of 960 mg per pound of refined wheat flour. In order to meet U.S. FDA guidelines, enriched flour may not contain more than 5% by weight of wheat germ or partly defatted wheat germ.

In a current embodiment, the coarse fraction includes at least one of: bran and germ. For instance, the germ is an embryonic plant found within the wheat kernel. The germ includes lipids, fiber, vitamins, protein, minerals and phytonutrients, such as flavonoids. The bran includes several cell layers and has a significant amount of lipids, fiber, vitamins, protein, minerals and phytonutrients, such as flavonoids. Further, the coarse fraction may include an aleurone layer which also includes lipids, fiber, vitamins, protein, minerals and phytonutrients, such as flavonoids. The aleurone layer, while technically considered part of the endosperm, exhibits many of the same characteristics as the bran and therefore is typically removed with the bran and germ during the milling process. The aleurone layer contains proteins, vitamins and phytonutrients, such as ferulic acid. Although the bran and the germ only make up about 18% of the wheat kernel by weight, they account for about 75% of the nutritional value of the wheat. In a current embodiment, the coarse fraction of the present invention may include: 38% fiber, 18% protein, healthy lipids, B vitamins, vitamin E, phosphorus, magnesium, selenium, manganese, zinc, copper, chromium, phytonutrients (phenolic acids, flavonoids, etc.).

Further, in an exemplary embodiment, the coarse fraction may be blended with the refined flour constituent. Preferably, the coarse fraction is homogenously blended with the refined flour constituent. Homogenously blending the coarse fraction and refined flour constituent may help reduce stratification of the particles by size during shipping. In present embodiments, the coarse fraction may be mixed with the refined flour constituent to form the whole grain flour of the present invention, thus providing a whole grain flour with increased nutritional value, fiber content, and antioxidant capacity as compared to refined flour. For example, the coarse fraction or whole grain flour of the present invention may be used in various amounts to replace refined or whole grain flour in baked goods, snack products, and food products. The whole grain flour of the present invention (i.e. —ultrafine-milled whole grain flour) may also be marketed directly to consumers for use in their homemade baked products. In an exemplary embodiment, a granulation profile of the whole grain flour is such that 98% of particles by weight of the whole grain flour are less than 212 micrometers. For example one embodiment might have a first portion where 2-30% of the particles by weight are between 150 and 212 micrometers, a second portion including the first portion where 30-90% of the particles are more than 75 micrometers, a third portion where including the second portion where 65-95% of the particles by weight are more than 38 micrometers, and a fourth portion where 0-30% of the particles by weight are less than 38 micrometers. Another embodiment might have a first portion where 0-35% of the particles by weight are less than 38 micrometers, a second portion where 45-60% of the particles by weight have are between 38 and 75 micrometers, a third portion where 30-50% of the particles by weight are between 75-150 micrometers, and a fourth portion where 2-30% of the particles by weight are between 150 and 212 micrometers. In a further embodiment, the whole grain flour may include: a first portion including bran in a first proportion of at least substantially 14-16% by weight of the whole grain flour; a second portion including germ in a second proportion of at least substantially 2-3% by weight of the whole grain flour; and a third portion including endosperm in a third proportion of at least substantially 80-85% by weight of the whole grain flour.

In present embodiments, the refined flour constituent may have a first protein content in a first proportion by weight of the refined flour constituent. The coarse fraction may have a second protein content in a second proportion (preferably, at least substantially 18%) by weight of the coarse fraction. The blend of the refined flour constituent and coarse fraction may have a third protein content in a third proportion by weight of the blend, the third proportion being greater than the first proportion.

In further embodiments, whole grain flour of the present invention allows for increased antioxidant capacity over refined flour. Antioxidants may play a role in reducing the risk of cancer and other diseases. Thus, it has been recommended that individuals consume foods such as fruits, vegetables and whole grains that contain antioxidants. The antioxidant activity of food products can be measured by the ORAC (Oxygen Radical Absorbance Capacity) assay. The ORAC assay measures hydrophilic and hydrophobic antioxidant capacities of a food using fluorescein as the fluorescent probe and 2,2′-azobis(2-amidinopropane)dihydrochloride as the peroxyl radical generator. Using the ORAC assay, the total antioxidant capacity, including the capacity due to the nutritive (Vitamins A, C, and E) and other phytonutrients, including flavonoids, phenolic acids, and carotenoids in a food product can be readily determined. Antioxidants, such as flavonoids, may assist the body in helping reduce the risk of cancer. In a present embodiment, the refined flour constituent may have a first oxygen radical absorption capacity. Further, the coarse fraction may have a second oxygen radical absorption capacity. Preferably, the oxygen radical absorption capacity of the coarse fraction is at least 7,400 micromole Trolox Equivalents (TE)/100 g, which is comparable to the antioxidant capacity of wheat germ (8,400 micromole TE/100 g), and about three times greater than the average antioxidant capacity of refined wheat flour (1,450 micromole TE/100 g), (FIG. 9 a). However, the oxygen radical absorption capacity of the coarse fraction may be approximately 7,400 micromole TE/100 g, such as 6,700 micromole TE/100 g, prior to milling. Further, the blend of the refined flour constituent and coarse fraction (ex. —the whole grain flour of the present invention) may have a third oxygen radical absorption capacity that is greater than the first oxygen radical absorption capacity. For instance, the oxygen radical absorption capacity of the whole grain flour of the present invention may be 2,800 micromole TE/100 g. Use of the coarse fraction or whole grain flour in bakery, snack, and food products can increase the antioxidant capacity of the products. When compared on an equal weight basis with various fruits and vegetables, the antioxidant capacity of the coarse fraction is greater than blueberries, raisins, strawberries, spinach, broccoli and tomatoes. Of the fruits and vegetables tested, only artichokes and dried plums had a higher antioxidant capacity (FIG. 9 b). The increase in the antioxidant capacity of the coarse fraction of the present invention versus the coarse fractions of currently existing flours is due to the coarse fraction of the present invention having a comparatively lower moisture content.

In still further embodiments, the refined flour constituent may have a first fiber content in a first proportion by weight of the refined flour constituent. The coarse fraction may have a second fiber content in a second proportion (preferably at least substantially 20%) by weight of the coarse fraction and the blend of the refined flour constituent and coarse fraction (ex—the whole grain flour of the present invention) may have a third fiber content in a third proportion by weight of the blend that is greater than the first proportion.

In current embodiments, the refined flour constituent may have a first carbohydrate content, the coarse fraction may have a second carbohydrate content, and the blend of the refined flour constituent and coarse fraction may have a third carbohydrate content, the third carbohydrate content being less than the first carbohydrate content. Alternatively, the refined flour constituent may have a first carbohydrate content and the blend of the refined flour constituent and the coarse fraction may have a second carbohydrate content, with the second carbohydrate content being less than the first carbohydrate content.

In further embodiments, the refined flour constituent may have a first ash content, the coarse fraction may have a second ash content and the blend of the refined flour constituent and coarse fraction may have a third ash content of approximately 1.0-4.0% by weight of the blend of the refined flour constituent and coarse fraction. The ash content of flour is a measurement of the minerals present in the flour. Flour samples are incinerated and the ash that remains after incineration represents the minerals present in the flour. Wheat flours with a high mineral content will have a higher percent ash than wheat flours with a lower mineral content. Therefore, it follows that whole wheat flours will have a higher ash content than refined flours.

In still further embodiments, the refined flour constituent may have a first calorie density and the blend of the refined flour constituent and the coarse fraction (ex—the whole grain flour of the present invention) may have a second calorie density, with the second calorie density being less than the first calorie density. Because, the coarse fraction/refined flour blend has a higher insoluble fiber content, the coarse fraction/refined flour blend has a lower calorie density than the refined flour. Further, products which include the whole grain flour of the present invention may have a lowered calorie density due to the higher water absorption/retention as compared to refined wheat flour.

In exemplary embodiments, the coarse fraction (ex. —ultrafine-milled coarse fraction) is milled from an unmilled grain and includes a first fraction, which includes bran. The coarse fraction may further include a second fraction, which includes germ. In a current embodiment, the first fraction and second fraction of the coarse fraction may be milled to a particle size of less than 500 micrometers. For instance, the coarse fraction of the present invention may contain about 12% protein, about 7% fat, about 60-80% carbohydrates, and about 40% dietary fiber. The ash (mineral) content of the coarse fraction of the present invention may be about 6%, and may have an antioxidant capacity of about 7,400 micromoles Trolox Equivalents (TE)/100 g. (FIG. 8). Further, grain particle distribution of the coarse fraction may be substantially homogenous. In additional embodiments, the whole grain flour and/or the coarse fraction may include, but is not limited to at least one of: wheat, sorghum, milo, triticale, emmer, einkorn, spelt, oats, corn, rye, barley, rice, millet, buckwheat, quinoa, amaranth, African rice, popcorn, teff, canary seed, Job's tears, wild rice, tartar buckwheat, variants thereof, and mixtures thereof. In embodiments in which the whole grain flour and/or the coarse fraction includes wheat, the wheat may be durum, hard red spring, hard red winter, soft red spring, soft red winter, hard white, soft white, unclassed wheat, and mixed wheat.

In further embodiments, enzymes found within the bran and germ of the whole grain flour and/or coarse fraction are inactivated in order to stabilize the whole grain flour and/or coarse fraction. It is contemplated by the present invention that inactivated may also mean inhibited, denatured, or the like. Stabilization is a process that uses steam, heat, radiation, or other treatments to inactivate the enzymes found in the bran and germ layer. Naturally occurring enzymes in the bran and germ will catalyze changes to compounds in the flour, adversely affecting the cooking characteristics of the flour and the shelf life. Inactivated enzymes do not catalyze changes to compounds found in the flour, therefore, flour that has been stabilized retains its cooking characteristics and has a longer shelf life. For example, the present invention may implement a two-stream milling technique, as shown in FIG. 4, to grind the coarse fraction. In a present embodiment, after the coarse fraction has been separated from the refined flour, the coarse fraction is stabilized. Once the coarse fraction is separated and stabilized, the coarse fraction is then ground through a grinder, preferably a gap mill, to form a coarse fraction having a particle size distribution less than or equal to about 500 micrometers. (FIG. 4). In an exemplary embodiment, the gap mill tip speed normally operates between 115 m/s to 144 m/s, the high tip speed generates heat. The heat generated during the process and the airflow lead to a decrease in the microbial load of the coarse fraction as shown in FIG. 10. In further embodiments, prior to grinding in a gap mill, the coarse fraction may have an average aerobic plate count of 95,000 colony forming units/gram (cfu/g) and an average coliform count of 1,200 cfu/g. After passing through the gap mill the coarse fraction may have an average aerobic plate count of 10,000 cfu/g and an average coliform count of 900 cfu/g. Thus, the microbial load may be noticeably decreased in the coarse fraction of the present invention. After sifting, any ground coarse fraction having a particle size greater than 500 micrometers may be returned to the process for further milling.

In present embodiments, the unmilled grain may have a first aerobic plate count, the first fraction of the coarse fraction may have a second aerobic plate count, and the second fraction of the coarse fraction may have a third aerobic plate count. In exemplary embodiments, at least one of the second aerobic plate count and the third aerobic plate count may be substantially less than the first aerobic plate count.

In current embodiments, the unmilled grain may have a first coliform plate count, the first fraction of the coarse fraction may have a second coliform plate count, and the second fraction of the coarse fraction may have a third coliform plate count. In exemplary embodiments, at least one of the second coliform plate count and the third coliform plate count may be substantially less than the first coliform plate count.

In further embodiments, the coarse fraction may include: a protein fraction in a proportion of 18% by weight of the coarse fraction, a fat fraction in a proportion of 7% by weight of the coarse fraction, a minerals fraction in a proportion of 6% by weight of the coarse fraction, and an antioxidants fraction having an oxygen radical absorption capacity of at least 7,400 micromole TE/100 g of the coarse fraction.

In additional embodiments, the whole grain flour or the coarse fraction may be a component of a food product. For example, the food product may be a bagel, a biscuit, a bread, a bun, a croissant, a dumpling, an English muffin, a muffin, a pita bread, a quickbread, a refrigerated/frozen dough products, dough, baked beans, a burrito, chili, a taco, a tamale, a tortilla, a pot pie, a ready to eat cereal, a ready to eat meal, stuffing, a microwaveable meal, a brownie, a cake, a cheesecake, a coffee cake, a cookie, a dessert, a pastry, a sweet roll, a candy bar, a pie crust, pie filling, baby food, a baking mix, a batter, a breading, a gravy mix, a meat extender, a meat substitute, a seasoning mix, a soup mix, a gravy, a roux, a salad dressing, a soup, sour cream, a noodle, a pasta, ramen noodles, chow mein noodles, lo mein noodles, an ice cream inclusion, an ice cream bar, an ice cream cone, an ice cream sandwich, a cracker, a crouton, a doughnut, an egg roll, an extruded snack, a fruit and grain bar, a microwaveable snack product, a nutritional bar, a pancake, a par-baked bakery product, a pretzel, a pudding, a granola-based product, a snack chip, a snack food, a snack mix, a waffle, a pizza crust, animal food or pet food. In current embodiments, food products which include the whole grain flour or coarse fraction of the present invention may have an organoleptic profile substantially similar to a same food product made from the refined flour constituent in the absence of the coarse fraction. It is further contemplated that the whole grain flour or coarse fraction of the present invention may also be used as a means to increase the nutritional content of products that do not ordinarily contain grain flour.

In alternative embodiments, the whole grain flour or coarse fraction may be a component of a nutritional supplement. For instance, the nutritional supplement may be a product that is added to the diet containing one or more ingredients, typically including: vitamins, minerals, herbs, amino acids, enzymes, antioxidants, herbs, spices, probiotics, extracts, prebiotics and fiber. The whole grain flour or coarse fraction of the present invention includes vitamins, minerals, amino acids, enzymes, and fiber. For instance, the coarse fraction contains a concentrated amount of dietary fiber as well as other essential nutrients, such as B-vitamins, selenium, chromium, manganese, magnesium, and antioxidants, which are essential for a healthy diet. For example 22 grams of the coarse fraction of the present invention delivers 33% of an individual's daily recommend consumption of fiber. Further, 14 grams is all that is needed to deliver 20% of an individuals daily recommend consumption of fiber. Thus, the coarse fraction is an excellent supplemental source for consumption of an individual's fiber requirement. Therefore, in a present embodiment, the whole grain flour or coarse fraction may be a component of a nutritional supplement.

In a further embodiment, the nutritional supplement may include any known nutritional ingredients that will aid in the overall health of an individual, examples include but are not limited to vitamins, minerals, other fiber components, fatty acids, antioxidants, amino acids, peptides, proteins, lutein, ribose, omega-3 fatty acids, and/or other nutritional ingredients. Because of the high nutritional content of the coarse fraction of the present invention, there may be many uses of the coarse fraction beyond food that confer numerous benefits to an individual, including, delivery of fiber and other essential nutrients, increased digestive function and health, weight management, blood sugar management, heart health, diabetes risk reduction, potential arthritis risk reduction, and overall health and wellness for an individual.

In current embodiments, the nutritional supplement may further include a nutritive constituent. The nutritive constituent may have a first oxygen radical absorption capacity, the coarse fraction may have a second oxygen radical absorption capacity of at least 7,400 micromole TE/100 g of the coarse fraction and the nutritional supplement may have a third oxygen radical absorption capacity, the third oxygen radical absorption capacity being greater than the first oxygen radical absorption capacity. In further embodiments, the nutritive constituent may have a first fiber content in a first proportion by weight of the nutritive constituent, the coarse fraction may have a second fiber content of at least substantially 20% by weight of the coarse fraction (for instance, 38-40% for a whole wheat coarse fraction) and the nutritional supplement may have a third fiber content in a second proportion by weight of the nutritional supplement, wherein the second proportion is greater than the first proportion. Still further, the nutritive constituent may have a first calorie density and the nutritional supplement may have a second calorie density, the second calorie density being less than the first calorie density.

In exemplary embodiments, the nutritive constituent may have a first protein content in a first proportion by weight of the nutritive constituent, the coarse fraction may have a second protein content of at least substantially 12% by weight of the coarse fraction and the nutritional supplement may have a third protein content in a second proportion by weight of the nutritional supplement, wherein the second proportion is greater than the first proportion. In further embodiments, the nutritive constituent may have a first carbohydrate content and the nutritional supplement may have a second carbohydrate content, the second carbohydrate content being less than the first carbohydrate content.

In present embodiments, the whole grain flour or coarse fraction may be a component of a dietary supplement. The Code of Federal Regulations defines a dietary supplement as a product that is intended to supplement the diet and contains one or more dietary ingredients including: vitamins, minerals, herbs, botanicals, amino acids, and other substances or their constituents; is intended to be taken by mouth as a pill, capsule, tablet, or liquid; and is labeled on the front panel as being a dietary supplement.

In additional embodiments, the whole grain flour or coarse fraction may be a fiber supplement or a component thereof. Many current fiber supplements such as psyllium husks, cellulose derivatives, and hydrolyzed guar gum have limited nutritional value beyond their fiber content. Additionally, many fiber supplements have a undesirable texture and poor taste. Fiber supplements made from the whole grain flour or coarse fraction may help deliver fiber as well as protein, and antioxidants. The fiber supplement may be delivered in, but is not limited to the following forms: instant beverage mixes, ready-to-drink beverages, nutritional bars, wafers, cookies, crackers, gel shots, capsules, chews, chewable tablets, and pills. One embodiment delivers the fiber supplement in the form of a flavored shake or malt type beverage, this embodiment may be particularly attractive as a fiber supplement for children.

In current embodiments, the whole grain flour or coarse fraction may be included as a component of a digestive supplement. For instance, the whole grain flour or coarse fraction may be a component of a digestive supplement in combination with one or more prebiotic compounds and/or probiotic organisms. Prebiotic compounds are non-digestible food ingredients that may beneficially affect the host by selectively stimulating the growth and/or the activity of a limited number of microorganisms in the colon. Scientific evidence shows that consumption of prebiotic constituents in sufficient quantities may help manage digestive health, increase mineral absorption for bone health and improve immune function. Examples of prebiotic compounds within the scope of the present invention, may include, but are not limited to: oligosaccharides and inulins. Probiotics are microorganisms which, when administered in adequate amounts, confer a health benefit on the host. Examples of probiotic organisms within the scope of the present invention may include, but are not limited to: Lactobacillus, Bifidobacteria, Escherichia, Clostridium, Lactococcus, Streptococcus, Enterococcus, and Saccharomyces. In an exemplary embodiment the whole grain flour or coarse fraction may be a component of a digestive supplement which includes the probiotic organism, Lactobacillus GG (LGG). The combination of the whole grain flour or coarse fraction of the present invention and LGG produces a digestive supplement that may aid in overall digestive functions, may be used to improve overall health.

In further embodiments, the whole grain flour or coarse fraction may be included as a component of a functional food. The Institute of Food Technologists defines functional foods as, foods and food components that provide a health benefit beyond basic nutrition. This includes conventional foods, fortified, enriched, or enhanced foods, and dietary supplements. The whole grain flour and coarse fraction include numerous vitamins and minerals, have high oxygen radical absorption capacities, and are high in fiber, making them ideally suited for use in/as a functional food. Functional foods within the scope of the present invention may include, but are not limited to, one or more of the following: a bagel, a biscuit, a pudding, a bread, a bun, a croissant, a dumpling, an English muffin, a muffin, a pita bread, a quickbread, a refrigerated/frozen dough products, dough, baked beans, a burrito, chili, a taco, a tamale, a tortilla, a pot pie, a ready to eat cereal, a ready to eat meal, stuffing, a microwaveable meal, a brownie, a cake, a cheesecake, a coffee cake, a cookie, a dessert, a pastry, a sweet roll, a candy bar, a pie crust, pie filling, baby food, a baking mix, a batter, a breading, a gravy mix, a meat extender, a meat substitute, a seasoning mix, a soup mix, a gravy, a roux, a salad dressings, a soup, sour cream, a noodle, a pasta, ramen noodles, chow mein noodles, lo mein noodles, an ice cream inclusion, an ice cream bar, an ice cream cone, an ice cream sandwich, a cracker, a crouton, a doughnut, an egg roll, an extruded snack, a fruit and grain bar, a microwaveable snack product, a nutritional bar, a pancake, a par-baked bakery product, a pretzel, a snack chip, a snack food, a snack mix, a waffle, a pizza crust.

In exemplary embodiments, the whole grain flour or coarse fraction may be used in medical foods. Medical food is defined as a food that is formulated to be consumed or administered entirely under the supervision of a physician and which is intended for the specific dietary management of a disease or condition for which distinctive nutritional requirements, based on recognized scientific principles, are established by medical evaluation. The nutrient contents and antioxidant capacities of the whole grain flour and coarse fraction make them ideal for use in medical foods.

In additional embodiments, the whole grain flour or coarse fraction may also be used in pharmaceuticals. The whole grain flour and coarse fraction are high in fiber and have a very fine granulation making them suitable for use as a carrier in pharmaceuticals.

In current embodiments, delivery of the whole grain flour or coarse fraction as a nutritional supplement, dietary supplement or digestive supplement is contemplated via delivery mechanisms where the whole grain flour or coarse fraction is the single ingredient or one of many nutritional ingredients. Examples of delivery mechanisms include but are not limited to: instant beverage mixes, ready-to-drink beverages, nutritional bars, wafers, cookies, crackers, gel shots, capsules, and chews.

A current embodiment of the present invention is directed to a grain product. For example, the grain product may include a first fraction including bran, the first fraction being milled to a particle size of less than 500 micrometers. The grain product may further include a second fraction including germ, the second fraction being milled to a particle size of less than 500 micrometers. In exemplary embodiments, the grain product may be at least one of: a food product, a nutritional supplement, a dietary supplement, a fiber supplement, a digestive supplement, a functional food and a medical food, each of which is described above.

In an additional embodiment, a milling process may be used to make a multi-grain flour, multi-wheat flour, or a multi-grain coarse fraction. For example, bran and germ from one type of wheat may be ground and blended with ground endosperm or whole grain wheat flour of another type of wheat. Alternatively bran and germ of one type of grain may be ground and blended with ground endosperm or whole grain flour of another type of grain. In an additional embodiment, bran and germ from a first type of wheat or grain may be blended with bran and germ from a second type of wheat or grain to produce a multi-grain coarse fraction. It is contemplated that the present invention encompasses mixing any combination of one or more of bran, germ, endosperm, and whole grain flour of one or more grains. This multi-grain, multi-wheat approach may be used to make custom flour and capitalize on the qualities and nutritional contents of multiple types of grains or wheats to make one flour.

The whole grain flour of the present invention may be produced via a variety of milling processes. An exemplary embodiment of such a process is depicted in FIG. 11 and involves grinding grain in a single stream without separating endosperm, bran, and germ of the grain into separate streams. Clean and tempered grain is conveyed to a first passage grinder, such as a hammermill, roller mill, pin mill, impact mill, disc mill, air attrition mill, gap mill, or the like. In one embodiment, the grinder may be a gap mill. After grinding, the grain is discharged and conveyed to a sifter. Any sifter known in the art for sifting a ground particle may be used. Material passing through the screen of the sifter is the whole grain flour of the present invention and requires no further processing. Material that remains on the screen is referred to as a second fraction. The second fraction requires additional particle reduction. Thus, this second fraction may be conveyed to a second passage grinder. After grinding, the second fraction may be conveyed to a second sifter. Material passing through the screen of the second sifter is the whole grain flour of the present invention. The material that remains on the screen is referred to as the fourth fraction and requires further processing to reduce the particle size. The fourth fraction on the screen of the second sifter is conveyed back into either the first passage grinder or the second passage grinder for further processing via a feedback loop. In an alternative embodiment of the invention, the process may include a plurality of first pass grinders to provide a higher system capacity.

It is contemplated that the whole grain flour, coarse fraction and/or grain products of the present invention may be produced by a number of milling processes, including, but not limited to, those milling processes described herein and those milling processes set forth in U.S. Provisional Application No. 60/732,046 entitled: “A Process For Producing An Ultrafiber Product and Health and Wellness Products Thereof,” filed Nov. 1, 2005, and U.S. patent application Ser. Nos. 10/738,732, 10/945,199 and 11/211,864 filed on Dec. 17, 2003, Sep. 20, 2004 and Aug. 25, 2005 respectively, each entitled: “A Process for Producing an Ultrafine-Milled Whole-Grain Wheat Flour and Products Thereof,” each of the above-referenced applications being herein incorporated by reference in their entireties (See also: the Cross-Reference section above). In an embodiment, the yield is between about 97% and about 100% of the entire wheat kernel, other than moisture. Further, it is contemplated that the whole grain flour, coarse fraction and/or grain products of the present invention may be modified or enhanced by way of numerous other processes such as: fermentation, instantizing, extrusion, encapsulation, toasting, roasting, or the like.

As discussed above, the coarse fraction or the whole grain flour of the present invention may be used to replace refined wheat flour in the preparation of commercial products. For instance, by replacing between 20%-25% of the refined wheat flour with the coarse fraction of the present invention, the nutritional value of the refined wheat flour products may be increased to levels equal to the nutritional value of products made from whole grain wheat flour. For example, products made with the coarse fraction have the benefit of higher fiber, protein, lipids, vitamins, minerals, antioxidants and phytonutrient concentrations compared to products made from refined wheat flour. Further, such products will have less available carbohydrates and a lower calorie density than products made from refined flour. Such replacement has minimal effect on the texture and appearance of the products (i.e., allows the products to retain texture and appearance more similar to refined flour products). While any variety of wheat can be used, the use of white wheat varieties yield a product appearance more similar to products made with refined wheat flour, since white wheat has a lighter colored bran. In alternative embodiments, the nutritional value of the commercial products may be enhanced beyond that of whole grain wheat by replacing up to 100% of the refined flour with the coarse fraction of the present invention. In further embodiments, less than 20-25% of the refined flour may be replaced with the coarse fraction, yielding a product more nutritious than refined flour but less nutritious than whole grain flour. As previously discussed, the coarse fraction of the present invention may be used to replace refined wheat flour or whole grain wheat flour in numerous bakery, snack and food products. A number of examples of such products are set forth below.
